Hy

We're using Asp.Net Core to create a REST-Service with Swagger. We're hosting the service at a URL like this:

https://www.mywebsite.com/myservice

With the following code:

 applicationBuilder
 .UseSwagger()
 .UseSwaggerUI(c =>
 
 c.SwaggerEndpoint("../swagger/1.0.0/swagger.json"",title);
 c.DisplayRequestDuration();
 c.OAuthClientId(clientId);
 c.OAuthRealm(redirectUri);
 c.OAuthAppName("App");
 );

...the Swagger-UI is correctly loading at:

https://www.mywebsite.com/myservice/swagger/

But when I try to do a Request over the UI with the Execute-Button, I got a 404, because the UI tries to do the request without the /myservice/ in the URL:

https://www.mywebsite.com/v1/cars

instead of

https://www.mywebsite.com/myservice/v1/cars

How do I have to correctly configure the service, so that the Swagger UI Calls are also working?

Hint:

This should be done in a generic way (like the ../ of the UI), because we will deploy the service on different environments, so the www.mywebsite.com is not the same on each environment.

Thanks for your help!

Both Swagger and Swagger UI need to be configured with relative paths. For example, if I wanted the UI to be accessible at the root of the app (whatever that might be) and the JSON endpoint at swagger/documentName/swagger.json, my configuration would look like this:

// register the services
services.AddSwaggerGen(c => 
 c.SwaggerDoc("latest", new Info Title = "Web API", Version = "latest" ); 

...

app.UseMvc();

// Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseSwagger(c => 
 c.RouteTemplate = "swagger/documentName/swagger.json";


// Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.), 
// specifying the Swagger JSON endpoint.
app.UseSwaggerUI(c => 
 c.SwaggerEndpoint("swagger/latest/swagger.json", "DynaFile Web API");
 c.RoutePrefix = string.Empty; //To serve the Swagger UI at the app's root

And obviously my controllers don't need to know my app name either. For example:

[Route("~/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
